Śrīmad-Bhāgavatam · Text 2.7.21
Who is speaking and story frame
धन्वन्तरिश्च भगवान् स्वयमेव कीर्ति-
र्नाम्ना नृणां पुरुरुजां रुज आशु हन्ति ।
यज्ञे च भागममृतायुरवावरुन्ध
आयुष्यवेदमनुशास्त्यवतीर्य लोके ॥ २१ ॥
dhanvantariś ca bhagavān svayam eva kīrtir
nāmnā nṛṇāṁ puru-rujāṁ ruja āśu hanti
yajñe ca bhāgam amṛtāyur-avāvarundha
āyuṣya-vedam anuśāsty avatīrya loke
The Lord in His incarnation of Dhanvantari very quickly cures the diseases of the ever-diseased living entities simply by His fame personified, and only because of Him do the demigods achieve long lives. Thus the Personality of Godhead becomes ever glorified. He also exacted a share from the sacrifices, and it is He only who inaugurated the medical science or the knowledge of medicine in the universe.
